Problem
1. A gas mixture at 20?C, 125 kPa is 50% N2, 30% H2O, and 20% O2 on a mole basis. Find the mass fractions, the mixture gas constant, and the volume for 5 kg of the mixture.
2. A mixture of 60% N2, 30% Ar, and 10% O2 on a mass basis is in a cylinder at 250 kPa, 310 K with a volume of 0.5 m3. Find the mole and the mass fractions and the mass of argon.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
